A loudspeaker system for a vehicle may include a vehicle partition panel that separates an interior space and an exterior space; a loudspeaker device comprising a frame, a diaphragm elastically supported at the frame, and a driving device that is configured to provide driving power for operating the diaphragm; and an air chamber disposed between the diaphragm and the vehicle partition panel. The frame delimits a chamber side opening of the air chamber facing the vehicle partition panel, where the vehicle partition panel comprises a vehicle partition panel opening. The vehicle partition panel opening has an extension which is smaller than the diameter of the diaphragm and smaller than an extension of the chamber side opening. The loudspeaker device is fixed to the vehicle partition panel such that the chamber side opening and the vehicle partition panel opening overlap in an overlapping area and the chamber side opening adjoins the vehicle partition panel opening.
